Specication of Letters Patent.

Patented May 14, 1918.

Application filed December 6, 1916. Serial No. 135,430.

To all whom it may concern.'

Be it known that I, Tnnononn Swanson.I residing at Lynn Center, in the county of Henry and State of Illinois, have invented certain new and useful Improvements in Carpenters Vork-Benches, of which the following-is a specilication.

My present invention is particularly directed to improvements in work benches that are more especially designed for carpenters uses, and specically, my invention seeks to provide certain improvements on the work bench construction disclosed in my Patent #1,112,729, dated October 6, 1914.

Among other objects, my present invention has for its purpose to provide in a work bench construction, certain elements that may be produced as attachments in the nature of metal parts adapted for being sold as separate articles and which, with certain instructions how to assemble them. are designed to be readily applied to a wooden bench structure that can be readily put up by any carpenter.

ln my patented work bench structure, i'neans is provided for feeding a board into position for being planed or dressed and in such means is included a plurality of independently operated feed screw devices.

One of the objects of my present invention is to provide in the metal attachments, means whereby a single actuating crank operates to impart motion to all of the feed devices that adjusts the board to be dressed.

Another feature of my present invention lies in the improved means for mounting the planer whereby it may be readily adjusted for dressing a straight edge or for dressing the edge of the board at the desired angles.

lith other objects in view that will hereinafter' appear, my present invention embodies the peculiar features of construction and coperative arrangement of the parts fully set out in the following description,

specifically pointed out in the appended claims and illustrated in the accompanying drawings, in which:

Figure 1 is a perspective view of my improved work bench construction.

. Fig. 2 'is a longitudinal section of my improved work bench.

Fig. 8 is a cross section on the line 3 3 on Fig. 2, the hinged top being swung back to its pendent position.

F ig. 4 is a cross section of the complete bench on the line 4 on Fig. 2, and shoviing a board clamped for planing.

F ig. 5 is a cross section on an enlarged scale of the planing device, and illustrates the means for adjusting the said device at` an angle to the board being dressed.

Fig. 6 is a detail perspective view that shows the several metal parts that constitute the board holder or support raising and lowering mechanism.

'Fig'. 7 is a diagrammatic section that illustrates the means for clamping the board against the hanger member.

Figs. 8, 9 and 10 are detail views of parts hereinafter specifically referred to.

In my present construction of work bench, instead of using a number of longitudinal base timbers, as in my patented work bench referred to, a single longitudinal base timber 3 is employed, and the said timber rests upon a series of cross members 1, preferably three, as shown.

The timber 3, at suitable intervals, is

bolted to the cross members 4, and in the construction shown, it is located between the series of uprights or posts 2 2, it being of suiiicient width to snugly seat, at its opposite edges, against the opposite ones of the sets of posts 2 Secured to the timber 3 b v long cross bolts and nuts a.

Q /L0 designate bracing irons secured at their upper ends to the uprights 2 2 and at their lower end to the outer ends of the cross members 4 4. Similar bracing irons CO- 40 are fastened to the intermediate uprights 2 2 and the corresponding cross members 4 4,

1 1 designates the oppositely disposed guide timbers that form the guideway for the planing implement, hereinafter referred to, and each of the said guide timbers is provided with a pendent adjusting bolt 5, each of which passes through a bracket 50, one of which is mounted on each of the several uprights 2 2 and the said bolts carry adjusting nuts 51 that operate to hold the guides 1 1, the adjustment of which serves to hold the said guides 1 1 level.

The vertical guide bars 8 8 in my present construction each have elongated hori- Zontal slots 80 in their upper and lower ends for receiving bolts 81 that adjustably secure the said bars to the uprights 2 2. as is best shown in Figs. 2,y 3 and 4.

By securing the bars S4 in the manner shown and described they may be readily moved baclr and forth into the right position to square with the guide rails l.

The longitudinally extended bar in the present showing of my invention is located between the opposite sets of the uprights 2-2 and it forms a supporting membery upon which the board, whose edges to be planed or beveled, is edgewise supported, and the said bar at each end has a laterally projected bracket 1l-11, and each of the brackets has a threaded vertical aperture lil for receiving the vertically positioned adjusting screw shafts 13-13 on the lower end of each of which is secured a bevel gear and the said lower ends of the said shafts 13-13 are journaled in bearing brackets 14g-1421. Gears 43 mesh with beitel gears 42-i2 on a horizontally disposed operating shaftl el, one end of which extends beyond one end of the bench and Carries a bevel gear il that is held in mesh with a like gear Llo on a vertically extended cranhv equipped shaft il-a, as is clearly shown in TEig. l.

1n my patented bench structure before referred to, each screw shaft 13 is provided with a separate crank operated power mechanism. ln my present invention l have provided for operating the sev-eral shafts 13 simultaneously and under a single crank actuated means and to such end each of the brackets 14e-14 includes a right angled pendent portion leb apertured to form the bearino's for a horizontal shaft l1 which extends lengthwise of the machine and carries a pair of beveled gears Q -42 that mesh with pinons on the lower ends of the screw shafts 13-13 le designates a pinion mounted on the outer end of the horizontal shaft al which meshes with a pinion i5 on a shaft 45 mounted at one end of the machine and which is provided with an operating crank, as is shown in Fig. 1.

instead of providing a planer having side flanges, as indicated by 33 in my patentreferred to, l have provided an improved means for dressing the upper edge of the board, and the said means, which is bestillustrated in Figs. 4 and 5 of the drawings, comprises a planer, the blade 47 of which is mounted in the planer body in any improved manner.

e9 denotes a side member pendent from the cross or hanger bar 58. the latter being of suicient length to straddle and ride pipo; the upper edges of the side guides t one side, the planer body is hingedly connected as at 48, to the member 119, as is best shown in 5, by reference to which it will be also seen that the hanger bar 58, where it passes across the planer, is

L, Y readies formed with a forwardly bent portion 5Sa whereby to provide ample space for the ready rise and escape of the shavings during the operation of planing.

t that side opposite the hinged connection of the planer, the bar 58 is provided with a slot (i0 for the passage a curved extension 59 secured to the planer body, the adjusting of which, up and down through the. side slot GO, provides for setting the planer in a plane with the edge of the board to be trimmed or at an angle to the said edge, whereby to dress the edge of the board being worked with a bevel trim as desired.

ln my present construction of attachments for earpenters work bench, such as is shown in my patent before referred to, instead of using independently adjustable upper and lower clam i members for holding the board to be dressed against the guide members 8,

1 employ a single clamping mechanism thatV can be quickly adjusted for applying the desired sidewise clamping of the bard being operated on, and the said mechanism, best shown in Figs. 3 and 7 includes a number of lei-shaped pivot rods Gil, one member of each of which is pivotally connected with the inner edge of the respective standards 2 at the front side of the bench, while the other member of each of such rods 6e pivot-ally connects to laterally shiftable presser or clamping member 63 that extends lengthwise of the bench and is located above the brackets 1l, as is clearly shown in Figs. 3 and e.

The hand hold 65 is attached to the presser member 63 for pulling the said membe in the direction of its length to cause such member, by reason of the link connection 64 with the uprights 2-2 to swing inwardly tightly against the board 10 to be worked on (see Fig. e) and thereby hold the said board up against the guide members 8.

For holding the presser member 63 clamped up against the board, the said member 63 has a ratchet surface 90 that is engaged by a resilient stop pawl 91, as is indicated in Figs. 6 and 7.

ln my present construction, the bench board 2S has hinged members 30 attached to and extended entirely across the bottom of the board and connected, at one end, to hinged members 3l on the adjacent or inner side member 31X of the bench, the latter and Jhe outer side member having grooves `lY-S 1y in the upper edge thereof as indicated on li ig. l and, as in my patented work bench .ferred to, the board 28 is so hinged that tvhen swung back, it'hangs iiatwise over one side of the bench (see Figs. 3, e and 5).

At the head end, the board :28 has two longitudinally extended strap iron members and they are attached to the board by screws 5ba-52a and the outer ends of the said members 52 are angled as at 52b to eX- tend over and hold the cross or bit block 29 securely against the said head end of the board with its bit edge 29ZL projected for being engaged by the end of the fiat board, as it is held upon the table during the operation of planing the flat side thereof.

Bit block 29 is preferably of metal and it is riveted or otherwiseL made fast to the strap iron members 52-52.

From the foregoing description taken in connection With the drawings, the complete construction, the manner in which the several parts are operatively assembled and the advantages of the construction of my present invention Will be readily understood by those skilled in the art to which my said invention relates.

By reason of constructing the operative parts in the nature of metal attachments and forming them for being cooperatively combined, as shown, the said attachments may be sold independent of the bench structure and readily operatively applied by a earpenter in building the Wooden bench structure suc-h as is generally disclosed in the drawings,i under printed instructions.

The structural arrangement of the several attachments are such that they may be manufactured at such low cost that When applied to the Wooden bench or body structure, an effective and desirable Work bench is developed at a' small expense of material and time.

That I claim is:

l. In a Work bench of the character described; the combination of a framing that includes al plurality of oppositely disposed uprights, a horizontal guide member on the upper ends of each of the said oppositely disposed uprights, means for supporting the board to be placed edgeivise between the said guide members, the said means including relatively xedly held guidemembers and a longitudinally disposed bar that forms a. rest for the board to be planed, mechanism for clamping the board to be planed against the vertical guide members, the said mechanism including a clamping bar pivotally connected to the uprights at one side and adapted for being swung over and held clamped against the board during the operation of planing' the upper edge thereof, and further means for effecting vertical adjustment of the bar upon Which the board is supported.

2. As an improvement in Work benches of the character described in which is included a pair of longitudinally extended guides that form a runway for a planing implement, means for supporting a board for being' projected edgewise between the guides, crank operated power transmission coperatively connected with the board supporting means for intermittently moving the said means to lift the board up between the guides and other means for holding the board from lateral displacement during the operation of planing the upper edge thereof, the said means including vertical side guides laterally adjustable with respect to the board and engaging one face of the board and a longitudinally disposed presser bar that engages the other side of the board and devices for holding the bar to its adjusted position.
